Technical details

The vulnerability stems from client-managed authentication tokens without sufficient server-side validation (CWE-306, CWE-521). The device relies on client-side authentication logic that can be reproduced by unauthenticated users, allowing attackers to generate valid authentication requests and bypass authentication. The affected component is the web management interface of Ebyte NE2-D11 firmware FW-9167-0-11. An attacker with network access can exploit this vulnerability without authentication or user interaction to obtain administrative access. Additional flaws include cleartext transmission of sensitive information and plaintext exposure of credentials in the management interface. Vendor has acknowledged the vulnerabilities but has not released patches as of the advisory publication date.
